Mine didnt' stay there that long though, came back down and settled about the 12 o clock position.
Bothered me too, but no matter how much I tried by ragging the shit out of the car, leaving it idling for ages, I couldn't get it to do it again.
Mine does however regularly sit ever so slightly over or slightly under dead centre, irrespective of what the ambient temp is or how the car is being driven, and I have no idea why. My mechanic, who I trust, tells me not to worry about it because its a combined oil and coolant reading.
Doesn't help diagnose your situation I appreciate, but thought it might be reassuring to know you're not alone!

i believe mine occured after coding the instrument cluster because my gas guage and my oil temp gauge were both over shooting around the same amount but after a full restart they went back to there normal positions..
It is a oil temp gauge and not a coolant temp gauge though. On my 640 the oil temp never moves from the half way position even when i push on it or whatever meanwhile my 135i n54 pwrd stage 3 gets hotter the more you beat on it
